Abstract

The invention provides an intelligent device application program identification method based on TCP session length probability distribution and a random forest algorithm, for improving the identification accuracy under the condition that a training set and a test set are collected from different devices. The intelligent device application program identification method comprises the following implementation steps: obtaining a flow data set Tij generated by an application Appj on the intelligent equipment Si; screening the flow data Tij; obtaining a session sample set set Gij; obtaining a training set Vtrain and a test set Vtest; constructing a classification model set M; and obtaining an identification result of the intelligent equipment application. According to the intelligent device application program identification method, the complete TCP session length probability distribution is calculated and is used as the characteristic to identify the intelligent device application program,and the intelligent device application program identification method is used for solving the problem of low cross-intelligent device application program identification accuracy in the prior art.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a method for identifying an application program of an intelligent device, in particular to an application program identification method for an intelligent device based on a session length probability distribution and a random forest algorithm. Background technique [0002] Application program identification is a technology that identifies the types of application programs existing on the target device by extracting the unique characteristics of the application program. The technology can be divided into: 1) application identification in personal computers; 2) website identification; 3) application identification in smart devices. In recent years, with the gradual popularization of mobile smart devices around the world, the application information on mobile smart devices has begun to have higher and higher value. Therefore, research on application identification in m...
